Problems solved by technology

As a result, judicial personnel often cannot retrieve the trial elements they want to query when using it, or need to spend a lot of time to read and search one by one from a large number of pushed cases, which is not only time-consuming and laborious, but also inefficient
[0004] For the problems existing in the above-mentioned related technologies, no effective solution has been proposed yet

Embodiment 1

[0059] According to an embodiment of the present invention, a case retrieval method is provided.

[0060] Such as figure 1 As shown, the case retrieval method according to the embodiment of the present invention includes the following steps:

[0061] Step S101, extracting the case element information and presentation text in the case database, clustering the judicial dispute focus description text in the presentation text, and labeling and verifying the obtained cluster categories to form a dispute focus and element tag library ;

[0062] Step S102, based on the dispute focus and element tag library, correspondingly label the case file materials in the case database to form a case file dispute focus library with dispute focus tags and case element tags;

[0063] Step S103, constructing and training a case language retrieval model by using machine learning technology according to the dispute focus and element label database, and the case file dispute focus database;

[0064]...

Embodiment 2

Abstract

The invention discloses a case retrieval method and system, and the method comprises the steps: extracting case element information and an expression text in a case database, carrying out the clustering of a judicial dispute focus description text, and forming a dispute focus and an element label library; based on the dispute focus and the element label library, performing data corresponding labeling on the case file materials in the case database to form a case file dispute focus library; constructing and training a case language retrieval model according to the dispute focus and element label library and the case file dispute focus library; for case materials to be retrieved, determining conflict points in the case file materials through a topic conflict detection method based on case dispute focuses, and extracting dispute focuses matched with the case materials according to the conflict points; and providing a data retrieval service for a case material to be retrieved according tothe extracted dispute focus by utilizing the case language retrieval model. According to the invention, similar cases can be retrieved and pushed from the case dispute focus angle.

Description

technical field [0001] The present invention relates to the technical field of data retrieval, in particular to a case retrieval method and system. Background technique [0002] With the openness and transparency of social information, the trial results of cases have attracted more and more attention from the society. For the same case, the judgment scales of different judges are often different. If it is possible to recommend similar previous cases in a timely manner before a case is judged, it will undoubtedly serve as a good reference. [0003] In the context of the above, courts at all levels have gradually launched a similar case recommendation system. However, the existing recommendation system for similar cases generally uses a similarity calculation method based on a vector space model, and searches and pushes through search keywords. . As a result, judicial personnel often cannot retrieve the trial elements they want to query when using it, or need to spend a lot...
